Angelique Kerber
Angelique Kerber saved a match point in the first round of the 2016 Australian Open and won the title anyway, beating Serena Williams 6-4, 3-6, 6-4, the first woman to take a major after saving match point in round one. The season kept building: a Wimbledon final, Olympic silver in Rio, the US Open, and in September the No. 1 ranking at 28. The game behind it was pure counterpunching, a left-hander sliding low into the corners and turning defence into flat, angled winners.
She beat Williams again in the 2018 Wimbledon final, in straight sets, for the last of her 3 majors, one each in Melbourne, New York and London. She finished with 14 career titles and 34 weeks at No. 1, then stepped away in 2023 to become a mother, returned in January 2024, and made the Paris Olympics her farewell. Even the exit was defiant: a quarterfinal against eventual gold medallist Zheng Qinwen that ran to a deciding tiebreak, Kerber saving three match points before the end.
